太谷县的冬小麦每年都有二、三万亩因前茬腾地晚,整地质量差,种的迟,形成三类苗,成为拉腿田。1979年我们在朝阳等6个点试验“春化处理、冬麦春种”,比晚播的三类麦增产77-93％。春化处理的方法:1月下旬用30℃温水浸泡麦种12小时,捞出堆闷催芽。待种子露出白芽后,移到0-5℃的冷室堆放30-40天。如在水溶液中加入适量的钼酸铵和磷酸二氢钾,堆放时间则缩短1倍。堆放
Taigu County’s winter wheat every year two or three million mu due to the former Tengdi late, poor soil preparation, the late species, the formation of three types of seedlings, a leg up. In 1979, we experimented with “vernalization and winter wheat and spring wheat” in six spots such as Chaoyang and increased 77-93% of the yield of three types of wheat after sowing. Vernalization method: In late January with 30 ℃ warm water soak wheat 12 hours, remove the pile stuffy sprout. After the seeds are exposed white buds, move to 0-5 ℃ cold storage 30-40 days. Such as adding an appropriate amount of aqueous solution of ammonium molybdate and potassium dihydrogen phosphate, stacking time is reduced by 1 times. Stacked
